Turkish authorities have begun to seal off the houses affiliated with the faith-based, government-critic Furkan foundation in Adana province.

Early on Friday morning, police teams reportedly raided the apartments that are reportedly belong to students affiliated with the foundation which has recently been targeted by the Turkish government due to its critical stance. Students were forcefully evacuated and the buildings were sealed off by the police.

An Adana court in early February appointed trustees to the management of the foundation, and arrested at least 21 people including Alparslan Kuytul, president of the foundation.

Kuytul and other arrestees are reportedly accused of “disturbing public order” and “establishing a criminal organization.”

Units from the police’s anti-terror and anti-smuggling and organized crime departments reportedly raided the headquarters of the foundation in Turkey’s Adana province and home addresses of the suspects last week, forcing open its doors and storming the premises.

The police also raided the foundation’s branches in the Central Anatolian province of Niğde and the eastern province of Elazığ.

On April 22, police in Turkey’s Adana province attacked members of the Furkan Foundation after Kuytul announced opposition to a presidential system of governance proposed by the ruling party Justice and Development Party (AKP).

When a group of around 200 people, including women and children, gathered at Atatürk Park in downtown Adana and representatives of the foundation wanted to read out a press release to mark the Holy Birth Week of the Prophet Muhammad, police attacked them with water cannons and tear gas after warning them that their gathering was not permitted.

When members of the group insisted on continuing with the event, 50 people were detained and four others were taken to a hospital after suffering injuries during the police intervention.

Turkish authorities blames the Gülen group for the failed coup of 2016.
